Equivalent & Substitute Parts for TN2-6V

Part Overview

The Panasonic Electric Works TN2-6V is a general purpose relay with DPDT (2 Form C) contact configuration, rated for 1 A at 6VDC. This through-hole mounted relay features sealed construction and is designed for applications requiring reliable switching of low-voltage circuits. The product is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TN2-6V is determined by strict alignment of the following critical parameters:

• Coil Voltage: Must be 6VDC to ensure direct compatibility with existing circuit designs
• Contact Form: Must be DPDT (2 Form C) to maintain switching functionality
• Coil Current: Must be 23.3 mA to ensure proper operation with existing drive circuits
• Coil Resistance: Must be 257 Ohms for electrical equivalence
• Mounting Type: Must be Through Hole to fit existing PCB layouts
• Termination Style: Must be PC Pin for direct connection compatibility
• Coil Type: Must be Non Latching for identical operational behavior

The TE Connectivity Potter & Brumfield Relays part number 1-1462038-4 meets all critical substitution criteria. While this substitute offers enhanced specifications in contact rating (2 A versus 1 A) and switching voltage capability (250VAC/220VDC versus 125VAC/110VDC), it maintains full backward compatibility with the TN2-6V through identical coil parameters and contact configuration.

Engineering Selection Recommendations

The TE Connectivity Potter & Brumfield Relays 1-1462038-4 is the direct substitute for the obsolete Panasonic TN2-6V. Selection of this substitute is supported by:

• Active Product Status: The 1-1462038-4 is currently in active production, ensuring long-term availability and supply chain continuity
• Electrical Equivalence: Identical coil voltage, coil current, coil resistance, and switching timing parameters guarantee drop-in compatibility
• Enhanced Reliability: Hermetic sealing provides superior environmental protection compared to the original full seal design
• Compliance: Both REACH Unaffected and EAR99 classification maintained across the substitution
• Backward Compatibility: Identical contact form, mounting type, and termination style ensure PCB-level compatibility without modification

The substitute part offers superior contact rating and switching voltage specifications, providing additional margin for circuit protection without compromising the original design intent.

Frequently Asked Questions (FAQ)

Q: Can the 1-1462038-4 be used as a direct replacement for the TN2-6V without circuit modification?

A: Yes. The 1-1462038-4 maintains identical coil voltage (6VDC), coil current (23.3 mA), coil resistance (257 Ohms), contact form (DPDT), mounting type (Through Hole), and termination style (PC Pin). No circuit modifications are required.

Q: What is the difference in contact rating between these relays?

A: The TN2-6V is rated for 1 A maximum contact current, while the 1-1462038-4 is rated for 2 A. The substitute provides double the current capacity, offering additional design margin for the same application.

Q: Are the switching voltage specifications compatible?

A: The TN2-6V switches up to 125VAC or 110VDC maximum. The 1-1462038-4 switches up to 250VAC or 220VDC maximum. Applications designed for the original relay will operate within the substitute's voltage specifications.

Q: What is the difference in seal rating?

A: The TN2-6V uses fully sealed construction. The 1-1462038-4 uses hermetic sealing, which provides superior environmental protection and moisture resistance for long-term reliability.

Q: Are both relays suitable for the same operating temperature range?

A: The TN2-6V operates from -40°C to 70°C. The 1-1462038-4 operates from -40°C to 85°C. Applications within the original temperature range are fully compatible with the substitute.

Q: What packaging is available for the substitute part?

A: The 1-1462038-4 is supplied in tube packaging, suitable for automated assembly and component handling.
